Chapter 12, Problem 14ICA
Solid objects, such as your desk or a rod of aluminum, can conduct heat. The magnitude of the thermal diffusivity of the material determines how quickly the heat moves through a given amount of material. The equation for thermal diffusivity (a) is given by:
Experiments are conducted to change the specific heat (Cp) of the material while holding the thermal conductivity (k) and the density (ρ) constant. The results are shown graphically.
- a. What are the units of the constant 0.088? Simplify your answer.
- b. If the thermal conductivity of the material is 237 watts per meter kelvin, what is the density of the material?
- c. If the material has a density of 4500 kilograms per cubic meter, what is the thermal conductivity of the material in units of watts per meter kelvin?
